After NCS update, now errors and won't open

I’m getting this error in windows problem reports after updating NCS to the latest version (update prompt on opening the program a few days ago). I tried remove and reinstalling NCS. Removing the ProgramData Netcam folder, etc. Windows 7 x64.
Any help?

Error Report shows:
Faulting Application Path: C:\Program Files\Netcam Studio - 64-bit\NetcamStudioX.exe

There are new pre-requisites for this version. Check the download page for more into.

I also have a Win7 install which now fails to start. Was running fine until this last update. I went to the download page but couldn’t find any “pre-requistes” listed. I tried deleting everything I could find (AppData, ProgramData), reinstalling both 32bit and 64bit, but all fail to start with same log message. My error is in .NET:
